PURPOSE:To avoid engine stall and enhance characteristics such as the rate of fuel consumption, exhaust gas characteristic and driving performance by setting previously fuel increase values with different fuel increment characteristic, selecting either of them according to the condition of power transmission system's being on or off, and by conducting fuel increase after fuel-cut. CONSTITUTION:A judgement shall be made to know if the number of pulses NAFC of the crank angle signal, i.e. TCD signal, fed from the point of time when the fuel-cut is stopped has attained a specified level, for ex. eight. Another judgement shall be made to know if the counted number of pulses NAFC is larger than the number of cylinder 4, and further if the clutch switch is off. When this is judged to be off, the value for No.1 factor KAFC1 in accordance with the number of pulses NAFC is read out of No.1 table for fuel increase factors KAFC after fuel-cut. When the state is judged to be transmissible for the power No.2 increase factor KAFC2 in accordance with the number of pulses NAFC is read out of No.2 table. |
